  • Visual Studio 2005 - OleDbConnection throws "Invalid authorization specification" in Form Designer,

    - by Jason Dagit
    I have a form with an OleDbConnection object on it. This form fails to load in the Form Designer with the message: One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Invalid authorization specification at ADODB.ConnectionClass.Open(String ConnectionString, String UserID, String Password, Int32 Options) ... (stack trace continues into user code) I've tracked this down to the OleDbConnection string. If I hardcode in the server IP, username/password/dbinstance into the constructor of the GUI form then the form will load in the designer. At run-time it is not an issue because we require the user to provide the login details. The question: Is it possible to use the OleDbConnection and the Form designer without supplying the database credentials in the source code of the form? For example, is there a property of the OleDbConnection or Form that I can set so that it doesn't need to access the database during Form design? My concern is that if we ever move the database server or change the login that the code will stop working in the designer.

  • Visual Studio Web Application edit source while running like in Tomcat\Eclipse\Java

    - by Bryan Migliorisi
    In an ASP.NET Web Site project, I've always been able to make changes to the underlying C# code and simply refresh the page in the browser and my changes would be there instantly. I can do the same thing when working with Java and Eclipse - edit my Java source and refresh the page and my changes are there. I cannot do this in ASP.NET MVC though and it is a real downer - I have to stop the running process and make my changes, and then restart debugging. This is a huge waste of time. Am I doing it wrong? What is the best approach to ASP.NET MVC development?

  • Create Silverlight application in Blend then migrate to Visual Studio

    - by Mohit Deshpande
    I want to make a Silverlight application in Expression Blend because of the rich UI and navigation of Blend. But I want to store the Silverlight application in an ASP.NET MVC web project. When I try to make a new Silverlight application, the default web application is an ASP.NET Web application (or web site, if I'm wrong). Can I make a single Silverlight application (no web project) then import in an ASP.NET MVC application? How can I do this?

  • Visual Studio autoclean?

    - by kubal5003
    Hello, I have a solution with multiple projects - executable, library, and others(unimportant right now). Library contains EF entity classes and executable uses them. When I'm working on some code from the executable then every entity that I use is marked as an error and compiler says that I should check usings and references. Reference in the executable project is set to library project(not the dll itself). When I build the library project then everything gets back to normal, but when I start typing then it happens again. I could live with it, but intelli sense isn't working and that is quite a disadvantage. Any ideas?

  • VIsual Studio and Ajax Control Toolkit

    - by Steve
    In my web application VS 2008 solution, I have the AjaxControlToolkit.dll in my bin directory and a whole set of language directories for it (ar, cs, de,es, fr, he, etc...) I don't remember how the language directories got in there. If I am using other languages via the ACT, do I need these directories? If not, then I don't? When I do a rebuild solution, the dll (AjaxControlToolkit.resources.dll) in these directories disappear. If I need them, what do I need to do to keep them from being deleted during a rebuild?

  • Visual Studio "Any CPU" target

    - by galets
    I have some confusion related to the .NET platform build options in VS 2008 Does anyone have a clear understanding what does "Any CPU" compilation target is and what sort of files it generates? I examined the output executable of this "Any CPU" build and found that they are (who would not see that coming!) the x86 executables. So, is there any the difference between targeting executable to x86 vs "Any CPU"? Another thing that I noticed, is that managed C++ projects do not have this platform as option. I'm wondering why is that. Does that mean that my suspicion about "Any CPU" executables being plain 32-bit ones is right?

  • Need advice on organizing two WPF applications within one Visual Studio solution

    - by Tim
    I have a WPF application (KaleidoscopeApplication) organized as follows: Solution (6 projects) Cryptography (DLL) Rfid (DLL) KaleidoscopeApplication (buildable "startup project") Basically, KaleidoscopeApplication contains a bunch of resources (sounds, images, etc) and your standard WPF junk (App.xaml, App.xaml.cs, other xaml and code). I need to create a new application that is very similar to Kaleidoscope, but I'm not sure of the best way to organize. This new app will need access to much of the same code and resources as Kaleidoscope. Preferably, I would like to create a new project in the solution, then simply use the "set as startup project" to pick which app I want to build. However, will I be able to access (share) the Resources folder of Kaleidoscope? I know I will be able to access much of the code if I simply add a reference to the project and include a "using Kaleidoscope". But the resources I'm not so sure about. Is this the right way to organize or am I asking for trouble in the future? Thanks in advance!

  • Replacing string literal values in Visual Studio project templates

    - by Daniel A. White
    I notice when I create a project template from an existing project in my solution, it does a semi-string replace to update references. However, it does not replace string literals. It does update my web.config file, but not code files. The project template: namespace MyTemplateProject { class MyClass { public string GetStringValue() { return "MyProjectTemplate"; } } } The generated code when used as a template: namespace MyActualNewProject { class MyClass { public string GetStringValue() { return "MyProjectTemplate"; } } } How can I instruct the template maker to replace "MyProjectTemplate" wih "MyActualNewProject"?

  • Visual Studio Designer looses / ignores data

    - by Kempeth
    I'm writing my own control - a datagridviewcolumn that displays integer values as texts like the comboboxcolumn can but without showing the combobox unless the cell is edited. I'm mostly there but I have problems with the databinding. I managed to get the necessary properties to appear in the designer but every time I set the datasource and close the editor the changes are dropped. When I assign the same datasource later in code it works like a charm, I just would prefer not having to do that... public class DataGridViewLookupColumn : DataGridViewColumn { private DataGridViewLookupCell template; private Object datasource = null; private String displaymember = String.Empty; private String valuemember = String.Empty; private BindingSource bindingsource = new BindingSource(); public DataGridViewLookupColumn() : base() { this.template = new DataGridViewLookupCell(); } public override DataGridViewCell CellTemplate { get { return this.template; } set { } } [Category("Data")] [ DefaultValue(null), RefreshProperties(RefreshProperties.Repaint), AttributeProvider(typeof(IListSource)), DesignerSerializationVisibility(DesignerSerializationVisibility.Visible), ] public object DataSource { get { return this.bindingsource.DataSource; //return this.datasource; } set { this.bindingsource.DataSource = value; this.bindingsource.EndEdit(); } } [Category("Data")] [ DefaultValue(""), TypeConverterAttribute("System.Windows.Forms.Design.DataMemberFieldConverter, System.Design"), Editor("System.Windows.Forms.Design.DataMemberFieldEditor, System.Design", typeof(System.Drawing.Design.UITypeEditor)), DesignerSerializationVisibility(DesignerSerializationVisibility.Visible), ] public String DisplayMember { get { return this.displaymember; } set { this.displaymember = value; } } [Category("Data")] [ DefaultValue(""), TypeConverterAttribute("System.Windows.Forms.Design.DataMemberFieldConverter, System.Design"), Editor("System.Windows.Forms.Design.DataMemberFieldEditor, System.Design", typeof(System.Drawing.Design.UITypeEditor)), DesignerSerializationVisibility(DesignerSerializationVisibility.Visible), ] public String ValueMember { get { return this.valuemember; } set { this.valuemember = value; } } } EDIT: I experimenting I just found out that that original DataGridViewComboBoxColumn can be made to behave exactly like I wanted to. By setting the DisplayStyle to Nothing the combobox control is only shown in edit mode.

  • Visual Studio : Make files in a folder got to bin/debug and not bin/debug/folder

    - by CF_Maintainer
    Consider This: I have folder called \SQLCE35Dlls inside my solution. It has some dlls that are required for application to interact with a SQLCE database in a stand alone fashion [without sql server ce 35 install on the PC]. After a build, I want these files to go to bin/debug and not to bin/debug/SQLCE35Dlls/. Setting "Copy if Newer" creates the latter situation. I want the former. Is it possible to facilitate this or does this have to done as part of the installer script? [avoiding the solution of adding the dlls at the root level of the solution instead of inside a folder]. This is a Winforms project solution.

  • Visual C++ Assembly link library troubles

    - by Sanarothe
    Hi. I'm having a problem having my projects built in VC++ Express 2008... I'm using a library, irvine32.inc/lib. INCLUDE Irvine32.inc works for me at school (On already configured VS environments) by default, but at home (Windows 7 x64) I'm having a boatload of issues. My original post here was that a file that irvine32.inc referenced, in the same folder, 'could not be opened.' Added irvine folder to the include path for specific project, progress. Then I was getting an error with mt.exe, but a suggestion on the MSDN suggested turn off antivirus, and now project does build but when I run a program that does NOT reference anything in irvine32, it tells me repeatedly that my project has triggered a breakpoint, and allows me to continue or break. Continue just pops the same window, break loads another popup telling me that "No symbols are loaded for any call stack frame. Source code cannot be displayed." This popup lets me view the disassembly. I tested it with and without working statements, it just throws the same breakpoint on the first line of code. Now, if I run the program when it DOES require something from the include file, in this case, DumpRegs: INCLUDE Irvine32.inc .data .code main PROC mov ebx,1000h mov eax,1000h add eax,ebx call DumpRegs main ENDP END main This gives me 1main.obj : error LNK2019: unresolved external symbol _DumpRegs@0 referenced in function _main@0 1C:\Users\Cameron\csis165\Lab8_CCarroll\Debug\Lab8_CCarroll.exe : fatal error LNK1120: 1 unresolved externals This does NOT happen when I build a project from the book author's examples, which has the same include statement. I'm baffled. :(

  • advanced Visual Studio kung-fu test -- Calling functions from the Immediate Window during debugging

    - by kizzx2
    I see some related questions have been asked, but they're either too advanced for me to grasp or lacking a step-by-step guide from start to finish (most of them end up being insider talk of their own experiment results). OK here it is, given this simple program: #include <stdio.h> #include <string.h> int main() { FILE * f; char buffer[100]; memset(buffer, 0, 100); fun(); f = fopen("main.cpp", "r"); fread(buffer, 1, 99, f); printf(buffer); fclose(f); return 0; } What it does is basically print itself (assume file name is main.cpp). Question How can I have it print another file, say foobar.txt without modifying the source code? It has something to do with running it through VS's, stepping through the functions and hijacking the FILE pointer right before fread() is called. No need to worry about leaking resources by calling fclose(). I tried the simple f = fopen("foobar.txt", "r") which gave CXX0017: Error: symbol "fopen" not found Any ideas? Edit I found out the solution accidentally on Debugging Mozilla on Windows FAQ. The correct command to put into the Immediate Window is f = {,,MSVCR100D}fopen("foo.txt", "r") However, it doesn't really answer this question: I still don't understand what is going on here. How to systematically find out the {,,MSVCR100D} part for any given method? I know the MSVCR version changes from system to system. How can I find that out? Could anyone explain the curly brace syntax, especially, what are those two commas doing there? Are there more hidden gems using this syntax?

  • Problems referencing build output from TFS Build and Visual Studio

    - by pmdarrow
    Here's what I'm trying to do: I have two solutions - one for my main application and its associated projects and another for my database (VS .dbproj) and its associated projects. What I'd like to do is include the output from the database project (a .dbschema and some SQL scripts) in my WiX installer (which exists in the main application solution.) This involves having TFS build the DB solution immediately before the main application solution. I've got that part working properly, but I'm having trouble referencing the output of the DB solution from my installer. I'm using relative paths to reference the DB project output in my WiX installer (e.g. <?define DBProjectOutputDir = "..\..\MyDatabaseSolution\MyDatabaseProject\sql\"?>) which works fine locally, but fails when building via TFS build. This is because TFS Build apparently changes the output dir of each project to one common location. Instead of the path to my database project being ..\..\MyDatabaseSolution\MyDatabaseProject\sql\ like it is when building locally, it gets set to something like ..\..\..\Binaries\Release\. How can I get around this and have a consistent output location to reference from my installer project? I'm using TFS 2005 and VS 2008.

  • SVN Repository folders don't match my solution folder structure in Visual Studio or folder structure

    - by Carlos
    I have a .NET solution which was badly organised, so I moved some projects around to appropriate folders. In the solution, I simply fixed the paths to the new locations, and everything is working in my working copy. I used AnkhSVN to commit the solution to the repository, which worked out fine as well. However, when I look in the repo explorer, the folders inside are organised in the old way. What do I need to do?

  • Error while creating tests in Visual Studio

    - by Benjol
    When I try to generate a unit test for the following method (in a public static class) private static string[] GetFields(string line, char sep) { char[] totrim = { '"', ' ' }; return line.Split(sep).Select(col => col.Trim(totrim)).ToArray(); } The Tests output says: While trying to generate your tests, the following errors occurred: This method or property cannot be called within an event handler. It works if I make the function public - I've tried running Publicize.exe manually, it doesn't complain, but doesn't make any difference either.

  • Compiling my own PHP extension on Windows with Visual Studio 2008

    - by Mickey Shine
    I wrote a PHP extension and it could be compiled and run under linux successfully. But on windows, I met some problems. I did the compiling on windows according to http://blog.slickedit.com/?p=128 with PHP source version 5.2.10, and after the compiling it generated the dll file. But when I tried to use the dll file, it reported me the memory problems when starting Apache(Wamp server). And then I started the debugging process, it seemed that REGISTER_INI_ENTRIES() had problems. Here is the PHP extension source code, http://www.bluefly.cn/xsplit.tar.gz , and it works fine on Linux. But I also want to make it work on Windows. Sorry I am not a pro so that I hope someone can help me. Any help is appreciated and thanks in advance~

    I would like to reconfigure the StyleCop import path in my project file.
